CLIMATE ARCHIVE
Sediments Offer an Extended History of Fast Ice
Scientists used sediments to create a millennia-long archive of Antarctic fast ice. Along the way, they discovered that the freezing and thawing of this enigmatic ice appear to be linked to solar cycles.
Linking Space Weather and Atmospheric Changes With Cosmic Rays
Water-Cherenkov cosmic-ray detectors can be used as a tool for monitoring and studying changes in the lower stratosphere over Antarctica.
Earth’s Climate May Go from Greenhouse to Hothouse
Uncertainty in climate models could mean Earth systems are perilously close to their tipping points, scientists warn.
The Endangerment Finding Is Lost
Tomorrow, the EPA will revoke the 2009 Endangerment Finding, finalizing a July proposal to do so, Press Secretary Karoline Leavitt said in a 10 February announcement.
The AMOC of the Ice Age Was Warmer Than Once Thought
An analysis of sediment cores indicates that North Atlantic waters were relatively warm and continued to circulate even under major climate stress during the Last Glacial Maximum.
Why Are Thunderstorms More Intense Over Land Than Ocean?
A new perspective on convective instability sheds light on the factors controlling intensity in the rising motions that produce precipitation, and occasionally thunder and lightning, over land.
Coastal Wetlands Restoration, Carbon, and the Hidden Role of Groundwater
Coastal wetland restoration offers major carbon benefits, and understanding groundwater processes helps explain how these ecosystems store carbon over the long term.
Snowball Earth’s Liquid Seas Dipped Way Below Freezing
Iron isotopes show that salty seawater pockets beneath the ice were as cold as −15°C.
Nationwide Soil Microbiome Mapping Project Connects Students and Scientists
Researchers and students are building a comprehensive picture of the microbial life beneath our feet.
Coral Diversity Drops as Ocean Acidifies
As seawater becomes steadily more acidic, complex branching corals die off and are replaced with hard boulder corals and algae.
